Thanks. Particularly interesting was the change reference in zone. I
wasn't aware of zone.
It appears as though the fromstring never appeared anywhere but there.
pyraf/iraf. All of this is unexplored territory to me. It looks like the
things I've learned here recently plus those will keep me busy for the
rest of the year. :-) Having the data files I've been working with
available now in fits is opening many vistas. Maybe pyraf has some
overview sampler of what it does? Since meteor work is my topic, maybe
they have special capabilites for such images?
I may have to stick closer to home for IP stuff though. That is, the
users of the s/w may not be able to absorb iraf easily, so it still
might behoove me to put a IP few features in the program in adding
analytic capabilities to.
